Hi;
Here's is the real {Honest-Answer}: Look in your owners manual and it will Spell it out for you and the time frame for all your services, Recommend by {Honda} the Manufacture that made your HCH II.
Or you can do what the dealer tells you to do.
Now, think about it? Who do you really want to put your trust in?
HTH:
Terry
BTW; I work for a Dealer, do you think I know Who you should Trust?
